The histological structure of the epidermis, nervous system, and musculature of the vestimentiferan worm Oasisia alvinae is examined. The differentiation of the integument of different regions of the body and the histological structure of the pyriform glands and papillae with cuticular plaques are described. All the main elements of the nervous system lie in the thickness of the epidermis. The brain structure is examined and an attempt is made to homologize parts of the vestimentiferan brain with the polychaete brain. Part of the vestimentiferan brain above the intrabrain channel corresponds to the supraesophageal ganglion of polychaetes, while part of the vestimentiferan brain under the channel corresponds to the subesophageal ganglion. Two commissures are located in the brain region that corresponds to the supraesophageal ganglion. These commissures could be related to the ventral and dorsal roots of the circumesophageal connectives of sedentary polychaetes. Bundles of fiber occur, which presumably correspond to the circumesophageal connectives and the transverse commissure inside the subesophageal ganglion. The musculature differentiation in the trunk region is a characteristic feature of O. alvinae, i.e., feather-like muscles that occur only in the anterior part of the trunk.
